Multifunctional ecological vertical seam type fishway beneficial to eel migration
The invention discloses a multifunctional ecological vertical seam type fishway beneficial to eel migration, which comprises a fishway inlet, a fishway retaining wall, a fishway bottom plate, a fishway outlet and vertical seam partition plates for dividing the fishway into a plurality of pool chamber units, and a plurality of bundles of vertical brushes are arranged on the fishway bottom plate at the vertical seams of the vertical seam partition plates; and gravel-cobble layers or nylon nets are alternately laid on the fishway bottom plates in the plurality of pond chamber units. Brushes are arranged at the bottoms of the vertical seams, so that eels can climb and shuttle among the brushes. According to the characteristic that eels can adhere to wet rough building wall faces to move upwards, gravel-cobble layers and nylon nets are laid in all pond chambers at the bottom of the fishway at intervals, the gravel-cobble layers can change the bottom water flow microhabitat, create bottom turbulent flow and weaken impact of water flow on the eels, and meanwhile concave-convex gaps are formed by the gravel-cobble layers so that the eels can conveniently swim and climb. The bottom nylon net can change the bottom of the pond chamber into a rough bottom surface, so that bottom friction force is increased, and eels can conveniently adhere to the pond chamber to move upwards.
本发明公开了一种有利于鳗鲡洄游的多功能生态竖缝式鱼道，包括鱼道进口、鱼道挡墙、鱼道底板、鱼道出口和将鱼道分割成若干个池室单元的竖缝隔板，在竖缝隔板的竖缝处的鱼道底板上设置有竖向的多束毛刷，若干个池室单元中的鱼道底板上相间铺设卵砾石层或尼龙网。在竖缝处底部设置毛刷，供鳗鲡在其间攀附穿梭。根据鳗鲡类能够粘附于湿润的粗糙建筑物壁面向上运动特点，在鱼道底部各池室间隔铺设卵砾石层和尼龙网，卵砾石层能够改变底部水流微生境，营造底部紊流，减弱水流对鳗鲡类的冲击，同时卵砾石层形成凹凸间隙便于鳗鲡类游动攀附。底部尼龙网能够将池室底部变为粗糙底面，增大底部摩擦力，方便鳗鲡类粘附向上运动。
